Tech billionaire Elon Musk has unveiled the “world’s safest flamethrower,” available for pre-order to prepare for a zombie apocalypse. Just in case, fire extinguishers are sold separately for an “exorbitant amount of money.”

Musk’s Boring Company – which has so far primarily specialized in “boring” tunnel construction – touted the new device on its official website on Saturday as a product “guaranteed to liven up any party!”

The handy device, which Musk says is “great for roasting nuts,” will cost die-hard fans of the SpaceX and Tesla founder a hefty $500. However, to embrace the fire power that could be quite useful in case of a zombie apocalypse they will have to wait until spring.

“When the zombie apocalypse happens, you’ll be glad you bought a flamethrower. Works against hordes of the undead or your money back!” Musk tweeted.

Just hours after the announcement Musk changed his Twitter profile description to “Zombie Defender” and dismissed what he says is a rumor of his “secretly creating a zombie apocalypse” to boost the demand for flamethrowers. He added that he lacked a facility able to produce so many zombies.

“You’d need millions of zombies for a so-called ‘apocalypse’ anyway. Where would I even get a factory big enough to make so many!?” Musk wrote.

The flamethrower will be shipped internationally, but delivery costs and taxes are not included in the price, the company said. A potential proud owner would also need to agree to terms and conditions, sent ahead of the flamethrower’s purchase.
